SH EET-METAL CHAIN.

SPECIFICATION forming part of Letters Patent No. 386,390, dated July1'7, 1888.

Application filed June 8,1888. Serial No. 276,443.

To all whom it may concern:

Be it known that I, FREDERICK Ec GE, a citizen of the United States,residing at Bridge port, in the county of Fairlield and State ofConnecticut, have invented certain new and useful Improvements inSheet-Metal Chains; and I do hereby declare the following to be a full,clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame.

My invention has reference to certain new and useful improvements insheet-metal chains, and has for its object to providea light andexceedingly strong chain; and with these ends in view my inventionconsists in certain details of construction and combination of elements,such as will be hereinafter fully set forth, and then specificallydesignated by the claims.

In the accompanying drawings, Figure 1 is an elevation showing a stripof scrap, as will be hereinafter explained, from which I prefer to makemy improved chain; Fig. 2, a detail of ablank cut from said scrap, Fig.3, a similar view showing said blank punched out at the center; Fig. 4,a side elevation of a chain made in accordance with my improvement, andFig. 5 a plan of the same.

Similar letters denote like parts in the several figures.

In the manufacture of sheet-metal chain under and in accordance withLetters Patent No. 202,528, issued to me April 16, 1878, the scrap whichremained after blanking the links from the metal strip was of suchconfiguration as to suggest the feasibility of cutting from said scrap asecond series of links for the formation of a light chain. I succeededin making several styles of chain from this scrap; but the presentinvention is an exemplification of the manner in which I first utilizedthis scrap, and, moreover, the chain thus produced can be made verycheaply, since I consume in its manufacture nearly all the scrapaforesaid.

(No model.)

The blanks A are cut from the scrap shown at Fig. 1, and a slot, B, cutlengthwise of the blanks and within the central portion thereof. A blankis folded so that the central portion forms an eye,C,whiletheheadsDregister. The heads D of this folded blank are now inserted within theslot B of astraightblank and given a quarter turn, so as to bring saidheads athwart of said slot,when the straight blank is folded after themannerof the preceding blank and the registered heads thereof insertedwithin the slot of a succeeding straight blank, these operations beingcontinued throughout the formation of the chain.

Of course I can cut suitable blanks from wholestoek; but I prefer toutilize the scrap as specified, sinceI am enabled to thereby form ahighly satisfactory chain at a greatly-reduced cost.

It will be readily understood that a sheetmetal chain constructed asabove set forth will not kink, and this is an advantage rarely met within acheap sheet-metal chain.

I claim 1. A sheet-metal chain formed from blanks having heads at eachend and a slot in the middle, said blanks being folded to constitutelinks, the heads of each link being connected to the succeeding linkthrough the slot in the latter, substantially as set forth.

2. In a sheet-metal chain formed from blanks having heads at each endand a slot in the middle, the links formed by folding the blanks so thatthe heads register, the heads of each link being inserted within andturned athwart the slot of the succeeding blank prior to the folding ofthe latter, substantially as shown and set forth.

In testimony whereof I affix my signature in presence of two witnesses.

FREDERICK EGGE.
